BEPCO's D4 Technology

Enhanced Emissions and Powertrain Testing

Back To All

The latest dyno control technology can help vehicle manufacturers meet global regulation standards and improve powertrain development efficiency and accuracy

Compliance with emissions standards is a central issue in vehicle certification globally. As most automotive OEMs produce vehicles for global clientele, compliance with different standards in each region creates burdens from an administrative and design standpoint. Vehicle makers have a strong interest in harmonizing emissions test procedures and performance requirements on a global scale. As such, stakeholders launched an initiative for a new global technical regulation on the Worldwide Harmonized Light Vehicle Test Procedure (WLTP) that aims to harmonize emissions-related test procedures for light-duty vehicles around the world.

BEP has been working with the WLTP in mind to create the latest technology, its Dyno Controller – generation 4 (D4). D4 is capable of light-duty vehicle certified emissions testing. It integrates and automates the new WLTP, SAE and EPA 1066 test procedures and dynamometer performance evaluations. With automated WLTP test procedures in place, risk for the customer is reduced and manufacturers can be assured that regulatory test requirements are met, wherever their cars are sold.

WLTP, SAE, and EPA 1066 test standards met by BEPCO's D4 Technology
The new D4 technology allows automakers to automate WLTP, SAE, and EPA 1066 test standards.

Today’s vehicles are equipped with multiple electronic control units throughout the engine and powertrain systems. The new BEP D4 Controller and Cell Controller platform are capable of interfacing directly with the vehicle’s computer system for vehicle troubleshooting, diagnostics and development. The D4 CAN bus interface is seamlessly built into the latest BEP Cell Controller software suite and test sequencer.

The new CAN bus interface can monitor values, setup faults and warnings based on internal control signals in the vehicle, as well as logging multiple channels of vehicle data. The D4 cell controller simplifies and automates the process of connecting to the vehicle and setting up the OBD2 communication strings and replies.

D4 Cell Controller allows complete customization of test sequences
The new D4 Cell Controller acts as the heart of the system, allowing complete customization of test sequences.

Vehicle testing needs are changing rapidly, and the D4 Cell Controller platform is designed to grow as testing needs evolve. New displays, controls, graphs and widgets can easily be added and configured by the operator at any time. Test sequences can be added or modified simply by dragging and dropping blocks using a flowchart-based design tool.

At the heart of the D4 Cell Controller platform is a Quad core industrial PC running the latest QNX real-time operating system. This is a mission-critical computer that runs a real-time test execution engine. This engine provides deterministic control of the test sequencing, displays, dynamometer, fan, driver’s aid, grade profile, robot, vehicle communications, logging and more. It also manages the easily configurable and extendable data acquisition and vehicle communications hardware.
